Abstract

The utility model discloses a hand type grain barn temperature tester for patrol inspection, which is composed of an inner core, a casing, and a panel. Measuring buttons and a digital displayer which can display a barn number and a temperature value are arranged on the panel, a computer communication port is arranged at the lower surface of the panel, and a jack is installed at the bottom of the casing. When the utility model is used, one man can hold the utility model by hands, an external plug of a thermometric cable of a grain barn is inserted into the jack, the measuring buttons can be pressed, and scores of or even hundreds of temperatures of the grain barn can be read in the utility model in one second. The utility model has the advantages of exact measurement, portability, convenient operation, convenient reading, material resources saving, and manpower saving. Automatic access record of measurement data can be realized, and the utility model is particularly suitable for the temperature measurement of a flow type grain barn.

Description

Hand-held grain temperature recycling testing apparatus

The utility model relates to a kind of measurement temperature device, especially a kind of device that is used for measuring silo grain temperature.

At present, the position of flow-type silo (Tu Yuan storehouse) is not fixed and is not had external power supply, its thermometric to be divided into two kinds.A kind of is original method, is inserted in the upper, middle and lower portion of silo respectively with glass tubular type thermometer, will extract the size that thermometer is had a look temperature in per tens hours, to prevent variable grain matter.This method will be given up a lot of artificial, and the people also is difficult for seeing accurately.Because per 1 Du Wenduge is very close, and each silo will insert tens thermometers, and is very heavy.Another kind of mode adopts the cable for measuring temperature formula, this kind mode be when silo when putting into grain several tens points, the warm spot of 200 points that have is put into each corner of silo respectively.Then receive outside the storehouse by lead.The work point of choosing does not then seal in the loop of warm cable with mA table, according to the variation of internal temperature and internal heat resistance and with the size variation of electric current, and the angular dimension of the beat of pointer by pointer gauge, and judge the height of temperature.This measuring method has following shortcoming: measuring sensor that has such as thermistor NTC, the variation of temperature and resistance is non-linear.And pointer mA table is linear, so reading is inaccurate and bring measuring error, is difficult for reaching the measurement authenticity.Especially winter, record was difficult more, if a grain depot has up to a hundred little silos to need the thermometric record, went down in one day so, and the survey crew of a grain depot is the people a lot.Wanted survey once in per three or four hours in spring and summer, to night inconvenient especially.

The purpose of this utility model is to provide a kind of carries, measures accurate, easy to operate, time saving and energy saving hand-held silo grain temperature measurement device.

The purpose of this utility model is realized by following technical scheme:

Whole device is made up of inner core, panel, shell, and panel is provided with the digital indicator of measuring button, storehouse number and temperature value, is provided with the computing machine communication port below the panel, and a jack is installed in the bottom of shell.Jack is made up of multi-core connector, can be the plug of multicore, also can be a multiple spot socket of being made by printed circuit board (PCB).

The utility model has changed the working method of the heaviness when measuring the Moveable granary temperature in the past, during use, only need this device of a personal hand-held, the male connector of the cable for measuring temperature of silo is inserted in the jack, press the measurement button, can be read into tens in this silo temperature to up to a hundred each points in the small-size computer in the instrument in one second, deposit among the computer A RM, send sound and light alarm simultaneously and represent to read in end by small-size computer CPU.It is accurate, easy to carry, easy and simple to handle that the utility model is measured, and reads the convenient automatic access record that also can realize measurement data, saved lot of manpower and material resources, is particularly suitable for the measurement of the temperature of flow-type silo.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the upward view of Fig. 1;

Fig. 3 is embodiment one of the present utility model;

Fig. 4 is embodiment two of the present utility model;

Fig. 5 is the internal frame diagram of single-chip microcomputer of the present utility model.

Below in conjunction with embodiment the utility model is described in further detail.

Embodiment 1: this device is made up of inner core, shell and panel, inner core is made up of electronic components such as singlechip CPU, be provided with storehouse button 3 on panel, the knob 4 of counting, measure button 5, temperature the Show Button 6, the top of panel is storehouse display 1 and temperature indicator 2.The bottom of shell is equipped with jack 8, and the multiple spot socket 9 that it is made by printed circuit board (PCB) when measuring certain number storehouse, is pressed storehouse button 3 and set certain number storehouse number; Need the measuring point number, just by the button 4 of counting, configure before the measurement, the external cable for measuring temperature 10 with this number storehouse during measurement is inserted in the jack 8, only need press and measure button 5, will show the temperature of silo each point automatically on the temperature indicator 6.After measurement is finished, come in the room, can show certain storehouse point temperature respectively by pressing the Show Button 6, if the given temperature standard that exceeds standard is arranged, show certain storehouse point temperature value that exceeds standard automatically.This instrument also has and the host computer communication function, and the communication port 7 automatic and host computer communications below panel show a some temperature of all silos automatically at host computer, and printable file.

Embodiment 2: the jack 8 of the bottom of this crust of the device is by connection cable and its partial installation, and the multi-pin connector 11 of drawing is connected with the external cable for measuring temperature of silo.Other is the same.
